Useful but a little buggy
Usually does a great job of staying out of the way, and the consistent breaks definitely help my pain. However the CPU usage sometimes goes way up for no apparent reason, causing my Mac to get hot and the fan to get annoyingly loud. Also it sometimes starts a break when Im watching a video full screen, so suddenly I cant seem to click anywhere.
